Description

[Detailed description of the invention] This invention relates to a seedling-raising sheet cover used for the germination of young seedlings.

Conventionally, in raising young seedlings, in order to prevent the paddy from lifting during the sprouting stage, seedling raising boxes are stacked in a multi-box style, the stacked seedling raising boxes are supported on a frame machine, and the seedling raising boxes supported on the frame machine are Seedlings are germinated either by heating and keeping them warm in a budding chamber, or by covering a frame supporting a seedling box with a sheet cover and heating and keeping the inside of the cover warm with a heating device installed below the frame.

As described above, in the past, it was necessary to manufacture a frame machine to support the stacked seedling growing boxes, and there were drawbacks such as the need for space to store and store the frame machine.

The present invention was made in order to solve the above-mentioned drawbacks, and a box-shaped cover 3 with an opening 2 at the bottom surface 1 is formed of an air-impermeable sheet, and a sheet wall 4 is provided inside the box-shaped cover 3. By providing a seat cover for raising seedlings, which is characterized in that the interior is partitioned into a plurality of rooms and a heating heater 5 is provided on the box-shaped cover 3 and the sheet wall 4, germination in raising young seedlings can be easily carried out using simple equipment. The purpose is to do something.

To explain the present invention based on the embodiment shown in the drawings, the box-shaped cover 3 is sewn into a rectangular box shape with an opening 2 at the bottom 1 of an impermeable sheet such as a vinyl sheet or a non-woven fabric, and an impermeable sheet is placed inside the cover 3. A sheet wall 4 is provided to form two chambers 3' inside the cover 3.

It is divided into 3' sections.

Each of the chambers 3', 3' partitioned by the sheet wall 4 serves as a budding chamber for covering and storing the stacked seedling boxes 6. The approximate planar area of each seedling growing box 6, that is, slightly larger than the outer shape of the seedling growing box 6, is formed so that a ventilation space S is created between the seedling growing boxes 6, and the depth thereof is sufficient to cover the stacked seedling growing boxes 6. It has a height of

A heating heater 5 is provided on the box-shaped cover 3 and the seat wall 4 to constitute a seat cover 7 for growing leather. ', 3' is sewn in a meandering manner on the inner surface, and the heating wire 5
A thermostat 8 is provided in the middle of ' to keep the heating temperature constant.

The reference numeral 9 in the figure is a support made of cross-sectional material, and the seedling box 6 is placed on the support 9 via a pedestal 10 so that the lower surface of the seedling box 6 and the upper surface of the support 9 are connected. Ventilation space S between
′.

Reference numeral 11 denotes a wall section erected on the outer periphery of the support stand 9, and the opening edge of the box-shaped cover 3 is brought into contact with the inner surface of the wall section 11 to close the opening 2 so as to maintain the heated state. This is to close the inside of the seat cover 7 to keep it warm.

Further, reference numeral 12 denotes a spacing member placed on the upper surface of the seedling raising box 6 to form a ventilation space S'' between the inner upper surface of each chamber 3', 3'.

13 is a power socket for the heating wire 5'.

Therefore, the seedling growing boxes 6, 6 stacked in several tiers are placed in parallel on the support stand 9 via the pedestal 10 while maintaining the required spacing, and then the spacing maintaining material 12 is placed on the top surface of the seedling growing boxes 6. In this state, the seedling boxes 6, 6 are covered and housed in each chamber 3', 3', and then the power socket 13 is inserted into the power source, and the inside of each chamber 3', 3' is heated by the heating heater 5. It is heated and kept at about 32°C to create the optimal atmosphere for germination.

In this case, each chamber 3', 3' heated by the heater 5
The air inside the chambers 3', 3' undergoes convection through the ventilation spaces s, s', s'', thereby uniformly heating and keeping the interiors of the chambers 3', 3' warm.

At this time, the box-shaped cover 3 can be supported by the stacked seedling growing boxes 6 via the spacing material 12, and the box-shaped cover 3 can be supported separately.
There is no need for a support frame or the like to support the stacked seedling growing boxes 6, and since the box-shaped cover 3 that stores the stacked seedling growing boxes 6 and the sheet wall 4 serving as the partition wall each have heating heaters 5, the stacked seedling growing boxes 6 can be raised easily. Uniform heating can be performed around the box 6.

Further, in this embodiment, the inside of the box-shaped cover 3 is partitioned into two chambers, but as shown in FIG. 4, the sheet wall 4 is provided in a cross shape to partition the inside into four chambers, thereby forming a large number of chambers. Of course, it is possible to do so.

Since this project is constructed as described above, it is possible to create a budding atmosphere similar to that of a conventional budding chamber by simply covering the stacked seedling boxes with a seedling sheet cover. Since there is no need to construct a bud chamber or use a frame machine, the overall structure can be made compact, and the work at the time of budding can be done easily, which has the effect of improving work efficiency.

In addition, the structure is simple, uniform heating can be performed around the seedling raising box, and seedlings can be raised accurately.
